In October 2011 work started on the world's largest Solar Bridge being constructed in the UK's capital, London. The solar array is being installed above the new platform at Blackfriars and will consist of in excess of 4,400 photovoltaic solar panels. The historic train station in London is in the process of a multi-million pound refit, which includes extending the platform along Blackfriars Bridge.

The project is due to be completed in 2012 and when it is complete the Victorian bridge will host London's largest solar array, approximately 6,000 square metres of photovoltaic solar panels. The panels are estimated to generate 900,000 kWh of electricity each year providing about half of the energy needed to power the station and reducing carbon dioxide emissions by about 510 tonnes a year.

Network Rail's project director for Blackfriars, Lindsay Vamplew has said that the refurbishment will set the standard for green stations around the world. "The Victorian rail bridge at Blackfriars is part of our railway history," he said. "Constructed in the age of steam, we're bringing it bang up to date with 21st century solar technology to create an iconic station for the city."

Network Rail has a plan to reduce carbon emissions by 25% per passenger kilometer by 2020, so the new solar bridge is a big step on the way to achieving this goal.
